escape any command aliases

e.g. if rm is aliased for 'rm -i', you can escape the alias by prepending a backslash:

rm [file] # WILL prompt for confirmation per the alias

\rm [file] # will NOT prompt for confirmation per the default behavior of the command

A simple directive which disables all aliases and functions for the command immediately following it. Shortcut for the bash built-in 'command' - "command linefoo".

Think, {sic}...

say, someone has aliased ls to 'ls --color=always' and you want to temporarily override the alias (it does not override functions)

Most distributions alias cp to 'cp -i', which means when you attempt to copy into a directory that already contains the file, cp will prompt to overwrite. A great default to have, but when you mean to overwrite thousands of files, you don't want to sit there hitting [y] then [enter] thousands of times.

Enter the backslash. It runs the command unaliased, so as in the example, cp will happily overwrite existing files much in the way mv works.

if you have a alias like this:

alias cp='cp -i'

# cp file1 file1.bak

equal to

# cp -i file1 file1.bak

(it will not overwrite file1.bak if it exist)

# \cp file1 file1.bak

equal to

# /bin/cp file1 file1.bak

(skip alias settings, it will overwrite file1.bak if it exist)

Know a better way?

What others think

This is particularly useful for 'rm', which many distributions insist on aliasing to 'rm -i' (ignoring the bad habits that this inculcates).

I usually type in the full path to the command to make sure I'm using both the unaliased command and also to make sure I'm not launching something out of /usr/local/bin/. Using full paths to commands is also a good habit for any scripts that may run with elevated privileges.

NOTE: Any type of quoting will work: backslash, single quote, double quote.

The Bash Reference Manual says "The first word of each simple command, if unquoted, is checked to see if it has an alias."

Thus, these will all execute the real unaliased rm command:

\rm file 'r'm file "r"m file 'rm' file "rm" file command rm file

The last example doesn't rely on quoting. Moreover, it will execute the rm command even if your defined rm as a function.

Why not use

command ...

or

builtin ...

... to make the selection with Bash? This also circumvents aliases and is safe for use in scripts.

Many distributions insist on 'rm -i' only as a root, and it's done for a good reason
